WRENCH.

SPECIFICATIOIT forming part of Letters Patent No. 352,518, dated November 16, 1886.

Application filed August 6, 1886. Serial No. 210,208.

To all whom it may concern.-

Be itknown that I, ALBERT A. COON, acitizen of the United States, residing at Hutsonville, in the county of Crawford and State of Illinois, have invented certain new and useful Improvements in \Vrenches, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to improvements in wrenches to rotate nuts and pipes, and also in devices to bear against the heads of bolts and retain them immovablewhile a nut is being V in use as a pipe-wrench.

secured upon the opposite end; and the objects of my improvements are to unite in a simple and inexpensive device the advantages obtained from three distinct implements, and this is effected by the construction and combination of the various parts and devices hcreinafter particularly set forth. I attain these objects by the implement illustrated in the accompanying drawings, in which- Figure 1 is aside view otthe tool constructed in accordance with my invention and in use as a nutwvrench. Fig. 2 represents the same Fig. 3 represents the same in use as a bolt-holder. Fig. 4. represents a modified form of the inner jaw and tionary jaw, A, made integral therewith, and

having its outer face at right angle to the side of the end A andbetween the jaw A and the handle A the lever-bar is provided with a series of teeth and notches, a, to receive into engagement the acute inner edge of a clevis, 0, that embraces the lever-bar, and to which clevis is pivoted at c the movable jaw G, the outer end, 0, of which is substantially at right angles to the body 0 of thejaw,

and is made of steel, and provided with acute teeth 0', for use as a pipe-holder. The end 0 of the movablejawhasaperforation,O alongside of its body for the passage of the end A of the lever-bar when the device is to be used asa nutwrench, as shown in Fig. 1. WVhen the device is to be used as a pipe-wrench, Figs. 2 and 4, the end A is withdrawn from the perforation c and the serrated end a made to bear against the side of the pipe, rod, or bolt, while the other side thereof is supported by the serrated end 0 of the movable jaw. WVhen the device is to be used asabolt-holder, Fig. 3, the parts assume substantially the same position as when used as a pipe-wrench that is, the end A is withdrawn from the perforation G", and the lever-bar is slid through the clevis until its serrated end bears against the bolt intended to be retained,while a nut is secured upon its point or said point is riveted down.

To retain the movable j awlocked upon a nut or other object placed between it and the stationary jaw, there is pivoted at d, to either side of the movable jaw, at a point nearly adjacent to the pivot of the clevis, athunib lever or look, D, to lock the clevis into engagement with the notches on the lever-bar, or to unlock it when it is desired to slide the said lever through the clevis. For this purpose the thumb-lever has on its inner side a notch, (1*, the sides of which are made to bear against the sides of the clevis, so that when in engagement, as in Fig. 1, the clevis is somewhat inclined, and the rear end of the movable jaw is made to bear against the back of the lever-bar,

and thereby retains the clevis into engagement with the teeth on said lever-bar. When the thumb part or outer end, (P, of the lever D is depressed until the sides of the clevis are at right angles with the lever-bar, the latter becomes unlocked and is free to be moved through said clevis. I

When the device is used as a pipe or bolt holder, the thumb-lever is pushed forward clear off the clevis and is out of the way.

Having now fully described my invention, I claim 1. A wrench consisting ofa lever-bar provided with notches along one side, a stationary a notch to engage with the clevis,su'bstantially 1o jaw, A, and one end provided with an acute as and for the purpose described. edge or teeth, in combination with a hinged In testimony whereof I affix my signature in jaw perforated as at 0 and a clevis, substan presence of two witnesses.
